The powerful assistant in open-pit coal mining – down-the-hole drilling rig

ニュース 9 Views
In open-pit coal mining, large-scale operations require efficient drilling equipment. Down-the-hole (DTH) drills, with strong adaptability and high drilling efficiency, become key equipment for open-pit coal mining. Although coal seams have relatively low hardness in coal mining, the overburden rocks show varying hardness, and DTH drills can flexibly cope with different lithologies.down the hole drilling rig

During the mining process:

 

  1. DTH drills can adjust drilling parameters according to coal seam thickness and rock characteristics. They quickly create blast holes with a diameter of 100-180mm and a depth of 10-15 meters for loosening and blasting overburden and coal seams.
  2. The dust removal system equipped on DTH drills effectively reduces dust pollution during drilling, improving the working environment and protecting workers’ health.
  3. This dust control meets environmental requirements, boosting green mining practices in coal mines.down the hole drilling rig
